Abstract

To study the compositional dependence of the optical properties and atomic structure of glasses, the $CdO-B_2O_3-SiO_2$ ternary glasses, which are known as highly photoconductive glasses, have been investigated. The photoconductivity of glasses containing CdO was investigated in a previous study, because of their potential applications in photoelectronic devices. The thermo-mechanical analysis and the Fourier transform infrared (FT-IR) spectra of the glass samples were measured to determine the structural variation of these glasses. Using transmittance measurements, we calculated the optical energy band gap. This paper presents results for control of the optical energy band gap 3.8 ~ 3.2 eV in cadmium-borosilicate glass system while the structural properties undergo monotonic changes.
